Philadelphia will need Owens

As another NFL season approaches, Scouts Inc. breaks down every roster and offers position-by-position breakdowns.

Donovan McNabb, coming off a superlative season, clearly has completed his evolution into a complete NFL quarterback. His biggest improvement: accuracy and pocket presence. McNabb still can buy himself time with his feet, throw on the run and scramble for yards, but he stays at home more often and waits for his receivers to get open.

Undoubtedly, wide receiver Terrell Owens provides a big, dependable target and has improved the offense's consistency, but he likely also has helped McNabb's confidence and patience in the pocket. The face of the organization and unquestionably the team leader, McNabb works well with his coaches and should continue to play at a high level.

Backup Koy Detmer might be listed as the No. 2, but he is more of a coach and mentor to McNabb than a viable fill-in. Detmer knows the offense front to back and is an accurate short-area passer, but lacks adequate mobility and arm strength. McMahon has much better physical skills and youth on his side, and likely would get the call in the event of a McNabb injury. He figures to officially be elevated to No. 2 as soon as he gets comfortable with the offense, and his upside is considerable.
